Check the polarisation of the protection: inject a three-phase symmetrical load according to
the following table:
IA IN 20°
Currents IB IN -100°
TEST 2
IC IN +140°
VAN 57 V 0°
Voltages VBN 57 V -120°
VCN 57 V +120°
• If one phase is missing the output Fuse Failure alarm will pick up & the LED general
alarm on the front panel will light up (see Fuse Failure description in section
